Ristretto JIT
Overview
Ristretto JIT provides a Just-In-Time compiler for the Ristretto VM. The JIT compiler generates native code from Ristretto VM bytecode, allowing for high-performance execution directly on the host machine. The library supports both standard platforms and WebAssembly targets with tailored compilation strategies. The appropriate compiler is automatically selected based on the target platform.
Architecture
The JIT compiler follows a multi-stage compilation pipeline:
- Bytecode Analysis - Analyzes Java bytecode for control flow patterns
- Control Flow Graph Construction - Builds a block based control flow graph
- SSA Transformation - Converts stack-based operations to Static Single Assignment form
- Native Code Generation - Generates optimized machine code
- Function Binding - Creates callable native functions
Features
- Fast execution through native code generation
- Automatic optimization of bytecode patterns
- Control flow graph analysis for complex branching logic
- Platform-specific compilation for x86-64, aarch64 (ARM64), s390x (IBM Z) and riscv64
- Comprehensive error handling with detailed error messages
Platform Support
The JIT compiler automatically adapts to the target platform:
- Native platforms:
- x86-64 (Intel/AMD 64-bit)
- aarch64 (ARM 64-bit)
- s390x (IBM Z Architecture)
- riscv64 (RISC-V 64-bit)
Limitations
Current limitations include:
- Only static methods and constructors (
<init>) are supported - Limited object-oriented features (no instance method compilation yet)
- No garbage collection integration
- Exception handling is not fully implemented
